IMPROVEMENT IN LOOMS.

I Specification forming part of Leiters Patent No. 137,077, dated March 25, 1873.

To all uhom it 'may concern:

'Be it 'known that I, CHARLES J. KANE, of y Milford, in the county of New Haven and State of Connecticut, have inventedy a new a-nd useful Improvement in Shuttle-Motions for Looms; and I do hereby declare that lthe following is afull, clear, and exact description ofthe same, reference being had to the accompanying drawing forming part of this specification, and in which- Figure 1 represents an irregular vertical longitudinal section of a narrow-ware loom having my improvement applied; Fig. 2, a top view of the shuttlerace and shuttle Fig. 3, an under view of the same, showing, also, the shuttle-drivin g mechanism; and Fig. 4l, a vertical section at the line :v x in Fig. 2.

Similar letters of reference indicate correspondin g parts. Y

This invention, which is more particularly designed to be applied to narrow-ware looms, consists generally in a novel construction and arrangement 4of the shuttle -operating mechanism, whereby, among other advantages, pro- In carrying out the invention, the loom may be constructed and organized to weave several webs at the same time, asis common with narrow-ware looms; but I propose, generally, with a View to running at greater speed, to construct and organize looms with my invention so that each loom shall weave only a single web. In any case, however, the raceway and shuttle-motion will be provided entirely v separate and distinct for the weaving of each web, and will be the saine either in a loom for weaving a single web, or in one for weaving Vtwo or more webs together, in the latter case merely requiring to be duplicated or multiplied according to the number of webs to be woven.

A in the accompanying drawing is the raceway, in which the shuttle B works. This race wa y is in the form of a circle, the' plane of which is parallel, or nearly so, with that in which the web C is woven, and perpendicular to the harness-motion D. Said raceway, which is stationary, for use in combination with a lay or heater, E, having a reciprocating motion, 1s made entirely open above and below, and with the bearing-surfaces b I) of the vshuttle formed by grooves and rabbets in opposite llnes, in a plane parallel with that in which the web is woven, or perpendicular to the harness-motion. In the outer edge of thei raceway there is an opening, c c, wide enough for the free passage of the warp w. rllhe shuttle consists of a thin, flat frame, the two sides o-f which are curved to correspond with the lbearing-surfaces b b, and the ends of which may be of straight or other form. The side which works in the inner bearing b has guides or slots u a in its under surface, to receive the shuttle drivers or fingers Gr G; and said side is preferably arranged to project slightly beyoud the other parts of the ends of the shuttle frame, to facilitate the entrance of the shuttle into the warp. The bobbin F, which carries the weft, is arranged lengthwise of the shuttle, to work in close proximity to the outer circle of the raceway. Parallel with the bobbin are one or more wires or rods, d', around which the yarn is wound, to produce upon it the necessary friction and tension as it passes from the bobbin to the eye e, which is arranged at' the center of the length of that side nearest the inner circle of the raceway. To the shuttle frame, also, is attached a frictionspring, f, which presses upon the'yarn on the bottom. The fingers ordrivers Gr G consist of two flat rods, which pass across each other through straight guide-grooves provided for their reception in a disk or boss, H, which works in a bearing in the raceway-plate I, said disk or boss being concentric with the circle of the raceway. The boss H has imparted to it an oscillating motion, by which the lingers G Gr, being carried back and forth with a circular motion by the boss, are caused to impart to the shuttle the necessary motion in the raceway. In the under side of the plate I, or in a plate secured thereto, is a stationary cam-like groove, l1l h i, shown in Fig. 3, the portions h It being corresponding arcs of circles, concentric with the raceway and shuttledriving boss H, and united by an offset, The fingers G G are each furnished with an anti-friction roll, k, which is received within the lcam-groove, and which runs therein as the fingers oscillate with the boss H.

As the rolls pass into and from the offset t' of the groove, they produce longitudinal movements of their respective fingers Gr, by which the latter are alternately withdrawn from and caused to reenter within their re-V spective guides or slots u u, such movements taking place atthe proper time to Withdraw each nger in turn from the shuttle in time to prevent it from coming in contact With the Warp, and to keep it out of contact during a suitable portion of its oscillating motion, to prevent its interference With the passage of the shuttle, one finger, G, at least, being a1- Ways in operation on the shuttle.

The boss H, carrying the fingers or shuttledrivers G G, may have its oscillating motion imparted to it by any suitable means, as, for instance, by an arm, m, and rod Z, operated by a lever, K, having its fulcrum at n, and gearing by a stud, o, With a revolving groove Wheel or cam, L.

Opposite to and in line with the opening c c in the raceway is a recess, r, for the entrance of the lay or beater E, which passes through the opening c c, crosses the stationary raceway, and enters the said recess r, to beat up the lling.

The harness D of the loom is intended to be arranged in a vertical position, as near to the ends of the platevI as is practicable,fal

lowing room for the lay or beater, which works in front of it, to pass back as far as is necessary from the raceway.

XVhat is here claimed, and desired to be secured by Letters Patent, is-

1. The oscillatin g and longitudinally-slidin g shuttle fingers or drivers G G, arranged in relation with each other and Witha circular raceWay for operation, in combination with a curvilinearly-reciprocating shuttle, substantially as specied.

2. The combination of the eurviliuearly-reoiprocating shuttle B, provided with slots or guides u u on its inner side, the circular race- Way A open above and below, and the oscillatingand longitudinally-sliding shuttle iingers or drivers G G, the Whole being arranged for/operation, in relation with each other and with the Warp, essentially as shown and described.
